Surprisingly simple given what appeared to be a complex ruleset. Very enjoyable.

it will be VERY hard to find the critical triple in the fog. therefore, it will be found useful for such puzzles to cover the entire grid with a YELLOW wash before starting.

!! this does NOT mean that you should WASH your monitor, or PAINT it yellow.
